(Pag. 162.) *Agelena gracilipes [= Liocranum gracilipes (Blackw.) 



1859]. 



Syn.: 1859. Agelena gracilipes Blackw., Descr. of six rec. disc. Spid., cet., in 



Ann. and Mag. of Nat. Hist., 3 Ser", III, p. 97. 

 1871. Drassus Palliardii Cambr., Descr. of some Brit. Spid., cet., p. 413. 



Under this species Cambridge cites " Leiocranum Palliardii L. 

 Koch", and calls it Drassus Palliardii; but as far as I am aware, L. 

 Koch has never yet described any spider under that name, and it 

 cannot therefore be taken up among the synonyms of the species 

 before us, much less displace the appellation under which it has 

 long been described and figured. Private specific and generic names 

 (so called "manuscript-names" or "in litteris-names", names derived 

 from private or public collections and the like) must not be con- 

 founded with names that have become the property of science, i. e. 

 such as have been fixed by descriptions or figures made public in 

 print, and with which alone in the registration pf synonyms and the 

 decision of questions of priority we have to do. Private names can- 

 not possibly be controlled either as regards the time when they 

 were imposed, or the species they indicate; and it does not require 

 much consideration to see to what abuses it would lead, if for ex- 

 ample everybody could make pretension to priority for a name, which 

 he chose to state that he had at some period or other given to a 

 species in his private collection, in preference to a denomination of 

 the same species subsequently to that period published in print and 

 definitively fixed by a description. Conf. Thor., On Eur. Spid., p. 5.

Cambridge loc. cit. has arrived at the same conclusion with my- 

 self, viz. that T. domestica Blackw. is identical with T. intricata
